Hi, I think my trusty 95era scooby has suffered a turbo failure, power is down and start up from hot produces a lot of smoke which does clear(sort of)but then reappears if I stop for a few minutes then restart, start up from cold is a bit three cylinderish then chimes on all four after a minute or so, does the turbo have seals in which can let coolant in as coolant level did drop also. The dump valve still lets off but boost seems poor compared to before. Thanks if anyone can advise a scoobynet newbie.
